Bikes or assualt squads

In general do you prefer bikes or assualt squads to fill your fast unit choices? It appears that assualt squads are more versatile and better able to take objectives but are not as shooty as bikes. Bikes seem like a lot of points/model. The only reaon I can see taking one would be to get a teleport homer to the front lines quickly. Not sure thats worth it with the new drop pod rules.

Assault Squads are for, surprise surprise, assaulting. Bikes are more oriented towards mobile firepower. They have twin-linked bolters, an array of special weapons, and an Attack Bike in tow. They put out dakka and keep moving while Assault Squads get stuck in asap. Also teleport homers never hurt.
